Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
1-(6-(2,5-Dimethoxyphenyl)-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)-2-methylpropan-1-amine (CAS 1706443-71-1), molecular formula C17H21N5O2 and molecular weight 327.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(6-(2,5-Dimethoxyphenyl)-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)-2-methylpropan-1-amine (C17H21N5O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
